Auxiliary tool for cable-stayed bridge steel anchor beam positioning and mounting, and using method thereof
The invention relates to an auxiliary tool for cable-stayed bridge steel anchor beam positioning and mounting. The auxiliary tool is characterized by comprising a tower-entering positioning plate anda tower-exiting positioning plate, the positioning plates are shaped like inverted T; the small-diameter sides of the positioning plates are embedded into a cable guide pipe, the diameter and the inclination angle of the positioning plates are the same as the inner diameter of the cable guide pipe, the large-diameter side of the positioning plate are provided with cover plates, the whole positioning plates can be tightly buckled on a tower-entering opening, and small holes are drilled in the center. The use method comprises the following steps: erecting an instrument; picking up the equipmentby holding a handle on the front surface of the positioning plate by a forward-looking measurer; airming at cable guide pipe entering (exiting) tower openings, enabling the positioning plates to be close to a pipe orifice, enabling the inner edge of the equipment to be attached to the cable guide pipe orifice and embedded into the cable guide pipe orifice until the positioning plate is matched with the pipe orifice and is completely clamped; enabling aligning of the tip at the bottom of the prism centering rod with the small hole in the center of the positioning plate; and measuring the centering rod after being leveled. The utility model has the advantages that a PVC hard board material and a practical design are adopted. The auxiliary tool has the advantages of simplicity in manufacturing, high precision, light weight, easiness in carrying and operation, no deformation, wear resistance, low cost, safety, reliability and the like.
本发明涉及一种用于斜拉桥钢锚梁定位安装的辅助工装，其特征是包括入塔定位板和出塔定位板，所述定位板呈凸字形，直径小一侧嵌入索导管内，直径和倾角与索导管内径相同，直径大一侧为盖板，整体能紧密卡扣在入塔口上，正中心钻有小孔。使用步骤分为：架设仪器；前视测量人员手持定位板正面的把手拿起设备;正对着索导管入（出）塔口，将定位板贴近管口，设备内沿贴合索导管口，嵌入进去，直至定位板与管口吻合，完全卡死；棱镜对中杆底部尖头对准定位板中心小孔位置，放置稳固；对中杆整平后方可测量。优点：采用了PVC硬板材料和实用型设计。具有制作简单、精度高，质地轻，易携带和操作，不变形，耐磨损，成本低，安全可靠等诸多优点。
